BEYONCE and Rihanna – wearing a sexy plunging black dress – partied until the early hours after MTV VMAs at a bash thrown by Jay-Z and Sean “Diddy” Combs.

Rihanna, who wore a casual t-shirt to the awards at the Barclays Center, switched to a super short cocktail dress and high heels.

The party, thrown by Jay and Diddy’s liquor brands D’Usse and Ciroc at PH-D rooftop lounge, was attended by Leonardo DiCaprio, who sat at a table with a host of models, Justin Timberlake, who bought along NSYNC members Chris Kirkpatrick and Joey Fatone as well as his wife Jessica Biel.
